Fuel Surcharge Calculator
Diesel goes up, your margin goes down. Bill the difference correctly.
Screen fuel surcharge per mile and total dollars on a load using three local planning patterns: standard formula, step pattern, and flat percent of linehaul. The app shows side-by-side outputs, an effective-rate chart, and source-boundary warnings tied to EIA diesel-price context. These are not carrier, broker, shipper, or DAT rate matrices, and the result is not invoice approval. Verify the rate confirmation, master transportation agreement, fuel addendum, paid-mile denominator, rounding, taxes, and settlement terms before billing.

-
Pick the program type
Choose standard formula, step pattern, or flat percent of linehaul. These are local planning patterns only; the written contract controls the actual program.
-
Enter current and base diesel prices
Use the contract index and date, an EIA national or regional on-highway diesel price, a fuel-card record, or another price basis named in the agreement. The base diesel value is also a contract term, not a universal default.
-
Enter truck MPG
Use the MPG specified by the program or a route-specific weighted planning MPG. A lower MPG increases the standard formula output, so this value needs contract or fleet-record support before billing.
-
Enter loaded miles, total miles, and FSC paid-on basis
Total miles = loaded plus deadhead. FSC Paid On determines the basis: most contracts pay FSC on loaded miles only, but some pay on all miles run for the shipper including deadhead to and from the pickup. Read the contract carefully.
-
For step patterns, enter the interval and rate
Step interval, step rate, base price, and rounding are private program terms. Enter them from the rate confirmation or fuel addendum before relying on the comparison.
-
Read the side-by-side reference table
The reference rows are generic pattern checks, not branded rate tables. Use them to spot assumptions that deserve contract review, then verify the actual written program before quoting or billing.
Built For
- Owner-operator screening a load against a written FSC program before accepting the rate
- Carrier or 3PL contract review comparing a proposed FSC program against a standard formula estimate
- Accountant or controller preparing questions before checking an FSC invoice line against the contract
- Owner-operator testing linehaul-only pricing when diesel is rising
- Hot shot operator setting their own FSC for direct-customer bidding on Permian or Bakken work
- Broker or dispatcher explaining an FSC assumption while keeping the contract terms visible
- New owner-op understanding why their take-home dropped when diesel jumped from $4 to $5 even though the load board rate did not change
Features & Capabilities
Three Planning Patterns
Standard per-mile formula, step pattern, and flat percentage of linehaul. Switch between them with one click while keeping the same source-boundary warnings.
Side-by-Side Pattern Comparison
Generic reference rows show how different assumptions move the estimate on the same load. They are not carrier, broker, shipper, or DAT rate matrices.
Effective Rate Chart Across Diesel Range
A line chart shows how the effective $/mile (linehaul + FSC) rises with diesel price from $2.50 to $6.00. A horizontal dashed line marks the without-FSC rate. The current diesel price gets a marker. Use it to communicate fuel risk to a customer or driver.
Margin Protection Output
Tells you in dollars per mile and total per load how much margin the FSC is protecting. A heavy FSC ($0.50 per mile or more) is real money against fuel volatility. A light FSC ($0.10 per mile or less) is symbolic.
Verdict Tier Coloring
No FSC, Light, Standard, Heavy, and Severe tiers based on the FSC per mile output. Helps you communicate FSC magnitude to customers and dispatchers without quoting raw numbers.

Comparison
| Program | Formula | Common Use | Pays Carrier Best When |
|---|---|---|---|
| Standard Formula | ($current - $base) / MPG | Planning estimate when contract terms match | Base price MPG and diesel index are verified |
| Step Pattern | floor(($current - $base) / step) x $/mi | Private fuel addendum or rate table | Step interval rate and rounding are verified |
| Flat Percent | % x linehaul revenue | Private linehaul-based FSC term | Linehaul inclusions and exclusions are verified |
